Each councils have their own rules regarding Driving License. Most of the council accept 1 year old UK DL and some maximum 3 years. Limits of points on DL varys council to council ,upto 5 or 6 points are acceptable for most of the councils. Criminal Record Bureau check is mandatory in UK. Application for Taxi DL is refused if you are convicted within 5 years or you have police caution depending on nature of crime. Now a days no one can disguise any claim history as all insurance companies have access to to central database to find the claim history or any insurance fraud etc.
My only concern is insurance premium which can go significantly higher than usual after 1 claim on fault.If someone can share his experience concerning insurance premium hike after on fault accident.
When I got my Taxi license, way back in the 80s, the rules at that time were....must have held a full UK License for at least three years.
Have a clean license, at the time of applying.
A police check was made for criminal offences.
(I wasn't a self employed driver, so the boss paid for the insurance, he told me that checks were made for previous insurance claims)
Then all I had to do was pass the Hackney driving test, and that was it. ;)
